Looks like a 36 Plymouth but the grill has stainless strips that clip into holes down the center bars.
I agree with Pat Thompson. It looks like a 36 Plymouth. But. Something is "off" about it. Is this a home-made item? It looks like it may be aluminum, from the pic. And the horizontal bar at the top, is a lot more curved from the factory.
No,it appears to be factory made and stainless. I didn't know if it could be Chrysler or Dodge or even for a pickup.
Could even be an old aftermarket replacement. JC Whitney and Western Auto sold grilles to fit most '30s-'40s cars that were just 'different' enough to get past the copyright and trademark lawyers... Posted using my Lil' Orphan Annie Secret Society Decoder Pin
